. To all whom, it may concern; Be it known that I, JAMES K. DELANO,
Jr., a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful. Improvements in Electric- Lighting Systems for Self-Propelled Vehicles; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters 0t ref erence marked thereon, which form a part of this specification. g
This invention relates to improvements in electric lighting systems for self propelled vehicles and consists of the matters hereinafter described and more particularly point-- ed out in the appended claims. I
In the use of an electric dynamo for light ing a self propelled vehicle, where said dy name is driven by the engine which drives the vehicle as, for example, in the case of an automobile, wherethe dynamo is driven by the gasolene engine, difiiculty is encountered on accountof the variable speed of the engine. If said, dynamo is geared to the engine so as to produce its normal output at one speed, the dynamo would be ruined when the engine attained a higher speed.
The object of the present invention is to obviate'this difiiculty and to provide a system including a dynamo driven by the engine in which means is provided for com pensat-ing for the speed of the engine so as to prevent any deleterious effect on the dynamh.
The advantages of the system will appear as I proceed with my specification.
The drawing representsa diagrammatic view of my improved system.
A indicates a dynamo which driven by the engine, (not shown in the drawing,) which propels the vehicle.
.A is the rotating armature of the dynamo, and B, B the field poles.
C is a shunt field coil which excites the armature in the usual way and C is a differential field winding opposed to the winding C. Said field windings are connected together by a loop J and the windingC is connected by a wire 0 to the main E, and the winding C by a wire 0 to the main E.
D, D are short circuited dampening field coils, the purpose of which will appear later.
E, E are the dynamo mains which lead to a storage battery F.
, the return main E is directly the dynamo and the storage battery is an iron core provided with a winding 9 in series with the dynamo and the storage battery, and with a winding 9 of higher resistance which is connected by means of wires 9 g across the mains E, E. An armature H, mounted on a pivoted interposed between SPIlIlg-COHUOllGCl aim H is arranged in position to be acted upon by said core G when the same is energized. Said arm H is con neoted by a wire H with the main E. A spring 72 is connected to the free end of said arm and normally holds the armature H away, from said core G, said spring being connected to a screw it about which it is adapted to be wound to adjust itstension. The arm H is normally held by the spring 72. in engagement with a contact I, the position of which. may be adjusted by means of an adjusting screw 1 A wire J connects the contact I with the loop J connecting the two field windings C, C.
K is an iron core interposed in the path of;
between the storage battery F and the dynamo. Said core is provided with winding K: which. is arranged in series with the battery F and a contact K", and with a winding k which is connected across the mains E, E by means of wires 75 Z0 An armature L is arranged in position to be attracted by the core K when the same is energized, said armature being mounted on a pivoted arm L which is connected by a spring L to a fixed adjusting screw Z. Said arm electrically connected to the return main E. The position of the arm L. with reference to the core K is determined by an adjusting screw stop Z against which it normally rests, being held in this position by means of a spring L When the core K is magnetized to attract the armature l1, it causes the arm L to engage against the contact K and thus connect the winding 70 to the main E From the battery F are led the lamp mains f, connected in the usual manner to lamps P. A switch f serves to throw the lamps in or out. The operation of the device is follows: When the dynamo started by the engine the current tiows throu h the mains E, E and from them through the shunt field C which is connected at one end to the main E and at the other end through theloop J wire J, the contact 1, arm H wire H to the main E. The core l'tl, energized by the coil said current is passing,
' the core G.
take it (which is connected as above described across the mains E, E attracts the armature L and causes the arm L to engage the contact K .thus establishing connection of the battery with the dynamo through the return main E When the dynamo is work ing at normal speed, the current passes into the storage battery F, through the coil 9 on As soon as the armature speeds up sons to produce a greater amount of current than required, the coil 9, through which energizes the magnet G sutli'ciently to draw the armature H toward it notwithstanding the opposite pull of the spring 71. By adjusting the spring 7 it is apparent that the point at which this will place may be exactly determined When this occurs the arm H swings away from the contact I thereby breaking the direct connection of the' field winding C with the mains and throwing in the diiferential field coil G which is then connected to the main E through the wire 0 and to the re down the field and thus turn main E through. the

field winding, cuts opposite to that of the until it has fallen to or amount whereupon the armature H will, under the action of the spring, swing away from the magnet G, and. thus return the connections to their initial position, ine armature H will vibrate forward and backward, maintaining the currentat the required amount, L
In theoperation of the armature H there is an abrupt change in the character of the field by reason of ti e change of the current from the field coil (3 to the opposing field coil G and retard this change-I use the short circuited dampening coils 13,13 which produce a lag in the magnetic-fields B, B vand this'inturn edects the current through the coil 9 on the core G, giving it a more uniform flow which results in a slow vibration of the arm H When the storage battery is fully charged its voltage is of course increased and the'potential of the dynamo is correspondingly raised. The highest otential of the dynamo effects the high res1stance coil 9 which is connected across the mains so as to increase themaguetic pull of the coieG on the armatureli, said coil having'the same effect as a weakening of the spring it. This cuts down the current flowing to the battery just as inv the case. where the dynamo exceeds the speed for its normal speed, the voltage of the battery exceeds t at o the dynamo and the current battery toward I This reverses the direction of the current through the coil is about the magnetic core K, which then acts cnt-ial field winding,
